Hey guys, hope everyone had a good Christmas full of family, drinks, and good times; be safe tonight on New Years'.
I own a Lazerer Rifle 1.6W and I've definitely been getting my usage out of it. However, as of late, I have noticed some issues with my spot and divergence.
Of course when I got the laser, it was fine. I removed the focusable lens and I cleaned both sides of the lens, and the piece just over the diode (don't know what it's called) - with a q-tip saturated with 91% alcohol. Let the alcohol dry and viola, a fresh clean new laser! Worked fine the first time.
I brought it out to show the family in the snow and such down here in Arkansas and it got a lil something in the lens, so I immediately took the q-tip back to it and repeated. Now though, I fear something is wrong
Take a look at these pictures and let me know what you think is wrong and what I can do to remedy this...
This is with the laser focused at its smallest point; a little hard to tell from photos, but around the dot itself, light is escaping and diverging all around.
This is with the laser at its most unfocused point before the lens is removed, note the "design" it has - this has been there for a few days now.
This is with the lens removed, note the typical "dots", you can see three of them here.
This is the interior side of the lens, which I swabbed thoroughly with a q-tip and alcohol, and was careful to make sure that no fibers were left behind. Not sure if this has anything to do with it, but note that just around the lens, there appears to be small chips in the metal - I don't know whether this would affect light properties or not.
Seen from a different angle
This is the inside, with the lens removed, diode visible. I also swabbed this thoroughly with q-tip and alcohol.
This is with the lens off after cleaning
This is with the lens on at the most unfocused point after cleaning (a little alcohol left, makes for cool effect as it is evaporated)
The lens after cleaning, after the alcohol has evaporated. Note how the "design" mentioned earlier is still present.
The lens at its most focused point after cleaning - Note that there is still light that is escaping around the dot, and escaping through the beam, making the laser less bright all around.
In conclusion, the "design" that seems to be causing this disappears for a few minutes after cleaning, and then reappears and causes the discrepancies once again - the dot has light escaping all around it and is not centralized as it should be; light escapes from the beam in-transit, because when I play with reflective, odd-angle surfaces, I notice that reflections can be seen before I point the beam at the surface. I have read through a few threads on this topic, but decided to share to gain some specific insight - if anyone has some ideas on what can cause this or how to fix it, I would be very appreciative. :thanks:
Also, I do not believe anything is burnt onto either the lens or the outside of the diode.
